Welcome Code when using SmartThings Hub from Home Connect

I have the SmartThings Hub from within Samsung Connect Home (3 Pack). Connect shows the SmartThings Hub is active. However, I want to use the SmartThings mobile App vs Samsung Connect. It asks for a (Welcome) Code to be entered to connect to the hub. Where do I get this? Samsung Connect Home does not include one in the packaging.

Thanks.
